(Reuters) ― A blast of super-cold arctic air is bringing dangerous sub-zero cold to the U.S. Midwest and Northeast as the system cartwheels through the Dakotas into Chicago, Illinois, and on to New England.
By Tuesday night and into Wednesday morning, Chicago will hit an astounding 20-to-25 below-zero Farhenheit, the National Weather Service said.
“This is dangerous, deadly cold,” said Richard Bann, meteorologist with the NWS’s Weather Prediction Center in College Park Maryland.
“Most of the snow will be in the Dakotas, the Twin Cities and Central Michigan, where they might get a foot or more,” Bann said.
“Upstate New York, Vermont and New Hampshire will see less than a foot.
Boston and cities in the east will get less than an inch.” “But it’s going to be cold throughout the east coast,” he said.
“Even parts of Mississippi and Alabama might see an inch or two of snow before this is over.” But Chicago will take the main brunt of the super-cold weather.
“An entire generation has gone by without experiencing this type of cold in the Chicago area.” said Mike Doll, a senior meteorologist at AccuWeather.
The agency’s Des Moines branch said “dangerous, life-threatening cold air” will impact Iowa from Tuesday morning through Friday morning, with wind chill values on Wednesday likely to range from minus 45 Fahrenheit to minus 55 Fahrenheit across the northern part of the state.
Delta Airlines said it would waive change fees for passengers affected by the winter weather in Chicago, Detroit and areas of the Upper Midwest.

London 27 March 2018: A new report from the Global Warming Policy Foundation (GWPF) counters media hype over recent warm global temperatures, showing that almost all of the sudden increase in temperatures in the last couple of years was caused by a record strong natural El Nino phenomenon rather than global warming.
In other words, they are warming more slowly than global warming theory says they should.
Since 2003 the average global temperature estimate based on surface weather stations has steadily diverged in the warm direction from satellite-based estimates without a convincing explanation.
The noticeable difference between the two data sets still has no broadly accepted explanation.

For example, regarding the climate system, every year there is more and more oil that goes into the ocean.
Over say the last 50 years the incremental temperature rise at the Poles has been generally greater than in the tropics.
And evaporation is linearly proportional to the wind speed, so this would tend to amplify warming from whatever cause by reducing evaporation … and where is the “source of heat” for that wind-related amplification of warming?
I can find ten scientists tomorrow who all claim they know why the Little Ice Age came about … the problem is, they all have different answers.
Given all of that, it is a giant and unsupported leap to think that we can say either that a) there’s been an increase in some kind of heat source, or b) whatever might have caused that increase in the heat source, it has in turn been the cause of the recent years of incremental warming.
The change in just absorbed solar radiation alone is more than enough to explain the entire change in total absorbed radiation at the surface … So per this particular individual analysis of the CERES data, the source of energy for the incremental change in temperature is … the sun.
The sun warms the ocean.

However, oceans rule the temperature of the planet, and as this most recent SST shows, there’s a lot of cool water and a clear signature of La Niña shaping up off the coast of South America: Source: http://www.ospo.noaa.gov/Products/ocean/sst/anomaly/ Ron Clutz of Science Matters writes: September Sea Surface Temperatures (SSTs) are now available, and we see downward spikes in ocean temps everywhere, led by sharp decreases in the Tropics and SH, reversing the bump upward last month.
HadSST is generally regarded as the best of the global SST data sets, and so the temperature story here comes from that source, the latest version being HadSST3.
The August bump upward was overcome with the Global average matching the lowest level in the chart at February 2015.
Also, note that the global release of heat was not dramatic, due to the Southern Hemisphere offsetting the Northern one.
Yet HadSST3 data for the last two years show how obvious is the ocean’s governing of global average temperatures.

. Researchers warn that unchecked fossil fuel emissions would raise global temperatures to catastrophic levels.
They reported in Nature Geoscience journal that they have a new estimate for the mass of fossil fuels it would be safe to burn, consistent with achieving the target agreed at the Paris climate conference in 2015. “Limiting total CO2 emissions from the start of 2015 to beneath 240 billion tonnes of carbon—880 billion tonnes of CO2–or about 20 years of current emissions would likely achieve the Paris goal of limiting warming to 1.5°C above pre-industrial levels,” said study leader Richard Millar, a climate system scientist at the University of Oxford.
And his colleague, Pierre Friedlingstein, the University of Exeter’s chair in mathematical modelling of climate systems, who advises the Intergovernmental Panel on Climate Change (IPCC) on carbon budgets, said, “Previous estimates of the remaining 1.5°C carbon budget based on the IPCC Fifth Assessment were around four times lower, so this is very good news for the achievability of the Paris targets.”
What had once been a stable ratio of around 280 parts per million of carbon dioxide has crept up to around 400 ppm in 2016, and global average temperatures are about 0.9°C higher than the pre-industrial average.
Almost as soon as the world’s nations settled on the Paris target, there were doubts about whether the temperature limit is achievable, and these doubts have been expressed by distinguished scientists at the forefront of climate change research.
That is not the same as twice the levels of carbon dioxide in the atmosphere: what is being measured here is the extra heat that double the carbon dioxide will guarantee.
Researchers in Texas and California said the “well below 2°C target” set in Paris commits the world to “dangerous” global warming, and a rise of 3°C on average for the whole globe would rate as “catastrophic.”

What actually happened in the sea during the solar eclipse!.
Last week, we wrote a teaser on what would happen in the sea during the eclipse.
But now the results are in and YES!
Sort of.
On August 21 2017, the moon passed in front of the sun, the sky darkened, the temperatures dropped, and the zooplankton thought it was night.
Bio-acoustic sonars detect particles and zooplankton floating in the water.
When the sound returns to the sonar, the signal is decoded and shaped into a vertical map of sound-reflecting stuff in the water.
When the eclipse happened, you can see that band start to rise, just like it does every dusk.
Was it truly an oceanographic calamity?

“Whenever there’s an extreme heatwave, people die — prisoners and nonprisoners alike.” All across the country, prisons and jails are not equipped with air conditioning, and when temperatures soar, inmates are often trapped in unbearable, life-threatening conditions.
In Texas, only 75 percent of state prisons have air conditioning.
In July, after inmates filed a lawsuit, a federal judge ordered air conditioning for vulnerable inmates at the Wallace Pack Unit, a prison one hour north of Houston that houses hundreds of elderly and disabled inmates.
Since 1998, 22 people have died in Texas prisons and jails because of heat-related issues.
By 2050, there will be 125 such days.
But an incarcerated person who may be experiencing the symptoms of heat stroke — nausea, confusion, or fainting — “is very limited in the steps they can take to cool down,” says Fathi.
As Mother Jones reported in 2015, valley fever can be lethal for certain populations who are more likely to be behind bars: “In California, the quirks of valley fever’s pathology have collided with the state’s habit of jailing a disproportionately large number of black and brown people.
For years, the California Department of Corrections and Rehabilitation housed many of these minority inmates in prisons scattered throughout the dusty, endemic areas of the Central Valley.
After inmates at a maximum security prison in Wisconsin filed a lawsuit over the facility’s extreme temperatures in 2000, a federal court ruled that the prison must install air conditioning in 2004.
But in the hottest states, air conditioning prisons is still an uphill battle.“It’s getting warmer and we’re having more and more periods of extreme heat,” Fathi says.
